Description

Realize method, base station and the user terminal of ascending resource scheduling

Technical field

The present invention relates to the allocation of radio resources field, particularly a kind of method, base station and user terminal of realizing ascending resource scheduling.

Background technology

In the wireless resource allocation mode of wireless access network, two kinds of different mechanism are used in uplink and downlink.Temporary Block Flow (TBF) is interim connection between travelling carriage (MS) and the network, only just exists in the process of data forwarding.It is supported in the unidirectional forwarding of the Packet Data Unit on the grouping physical channel.A TBF can go up at one or more Packet Data Channels (PDCH) and use Radio Resource.Network has distributed Temporary Block Flow indication (TFI) for each TBF, and in the TBF of Chu Xianing, the TFI of each TBF is different at the same time.The PDCH that network uses for the MS assignment by control information.On the descending PDCH that distributes, MS is by detecting the ownership that TFI discerns this TBF.On the up PDCH that distributes, MS determines the up PDCH that uses by monitoring the uplink state sign (USF) on the corresponding descending PDCH.Be that the corresponding different MS of each PDCH has different USF values, network determines by control USF which MS up PDCH returns use.

Transfer of data is radio block (Block) at the minimum scheduling unit of physical layer at present, each Block is made up of 4 time slots, and lay respectively at 4 continuous tdma frames, the propagation delay time of each time slot is the duration of a tdma frame in the Block, approximate 5ms, so the propagation delay time of each Block all is 20ms.For reducing this section time delay, minimizing Transmission Time Interval technology (RTTI) has been proposed.The RTTI overall thought is keep each Block big or small constant, reduces Transmission Time Interval (TTI) by utilizing multicarrier or multi-slot.

Time domain RTTI technology, referring to Fig. 1, B1 represents the basic Transmission Time Interval technology (BTTI) before the RTTI, and B2 represents RTTI.Wherein B1 is on 4 continuous T DMA frames, and every frame is with 1 time slot, and then the TTI of B1 equals 20ms; B2 is on 2 continuous tdma frames, and every frame is with 2 continuous time slot, and then the TTI of B2 equals 10ms.

Be that compatibility considers, up can multiplexing 10ms RTTI MS and 20ms BTTI MS, the position of USF can not change, and reads USF to guarantee that two kinds of MS can both monitor.Descending USF still is 20ms, but RTTI radio block that can dispatching uplink 10ms.

After introducing RTTI, for up RTTI TBF two kinds of USF patterns (mode) are arranged: BTTI USF mode and RTTI USF mode.When adopting RTTI USF mode, has only RTTI TBF; When adopting BTTIUSF mode, can RTTI TBF be arranged existing BTTI TBF again.Work as USF_GRANULARITY=1, to 4 granularity scheduling of up employing.

Referring to Fig. 2, under the BTTI USF mode:

That MS3 and MS4 adopt is BTTI TBF, and that MS1 and MS2 adopt is RTTI TBF.

For MS1 and MS2, (DL PDCH0) reads the USF1 of appointment on the MS1 PDCH that sequence number is lower in down channel in pairs during at block period Bx, just can be from comprising (Bx+1 on continuous 4 block periods that next block period Bx+1 begins, Bx+2, Bx+3, preceding 10ms Bx+4) sends upstream data; When MS2 during at block period Bx in down channel in pairs on the higher PDCH of sequence number (DL PDCH1) read the USF2 of appointment, just can be from comprising (Bx+1 on continuous 4 block periods that next block period Bx+1 begins, Bx+2, Bx+3, back 10ms Bx+4) sends upstream data.And network with 3 block periods after the Bx (Bx+1, Bx+2 Bx+3) go up on the lower or higher PDCH of sequence number USF retention (reserved USF) are set, MS1 and MS2 can ignore after the Bx cycle on 3 block periods the USF value on the corresponding PDCH.

For MS3 and MS4, when MS3 reads the USF3 of appointment at block period Bx, just can be from comprising that (Bx+3 Bx+4) sends upstream data for Bx+1, Bx+2 on continuous 4 block periods that next block period Bx+1 begins.When MS4 reads the USF4 of appointment at block period Bx, just can be from comprising that (Bx+3 Bx+4) sends upstream data for Bx+1, Bx+2 on continuous 4 block periods that next block period Bx+1 begins.

Referring to Fig. 3, under the RTTI USF mode:

The cycle of Block is compressed to 10ms, and MS1 reads the USF0 of appointment on PDCH pair when block period Bx, just can be from comprising that (Bx+3 Bx+4) sends upstream data for Bx+1, Bx+2 on continuous 4 block periods that next block period Bx+1 begins.

Some special business for example, as the VOIP business generally speaking, the every basically 20ms of user's voice bag sends once, and RTTI USF mode configuration can send a Block by every 10ms down.4 granularities of actual employing are divided timing, in distributing to 4 up of MS, owing to be every 10ms continuous dispensing, user speech bag for every 20ms transmission, only can use 2 (pieces of the preceding 10ms correspondence of each 20ms) at interval, other two (piece of the back 10ms correspondence of each 20ms) do not have data to send, and produces waste, reduces the utilance of channel.The 2nd and the 4th in the up channel in Fig. 3 (UL PDCH0 and PDCH1) is exactly two pieces that do not send data.If the every 40ms of user speech bag sends once, then use 4 granularities to distribute the waste that produces bigger.Equally, under the BTTI USF mode configuration, the every 40ms of user speech bag sends the waste that situation once also can produce channel resource.

Embodiment one, realizes the method for ascending resource scheduling, referring to Fig. 4, comprises the steps:

401, the base station issues the ascending resource assignment messages, comprise USF information and granular information in the ascending resource assignment messages, granular information is used to represent up granularity and assignment interval, and assignment interval is used to represent each transmission time interval of up in 1 granularity.

The base station can also be according to USF information and the granular information in the ascending resource assignment messages, issues to the descending block gap of dispatching uplink piece correspondence.When specific implementation, the base station can adopt following two steps to issue with realizing descending block gap:

402, the base station generates up schedule information according to USF information and granular information in the ascending resource assignment messages;

403, the base station is according to up schedule information, the USF of dispatching uplink piece correspondence in descending underground at interval.Adopt the scheme of present embodiment, the base station is according to assignment interval, and the compartment of terrain issues descending, like this, user data can send at interval up, has improved the probability of each up transmitting user data, thereby improved utilization rate of channel resources, avoided the waste of ascending resource.

Technical scheme in the present embodiment is applied on the different business, and the Transmission Time Interval of radio block can be different, and when being applied to the technical scheme in the present embodiment in the VoIP business, USF information is the relevant parameter of BTTI or the relevant parameter of RTTI; The relevant parameter of BTTI comprises mode parameter and the TFI radio block of BTTI USF; The relevant parameter of RTTI comprises mode parameter and the TFI radio block of RTTI USF.Up comprises BTTI radio block and/or RTTI radio block, and the Transmission Time Interval of BTTI radio block is 20ms, and the Transmission Time Interval of RTTI radio block is 10ms.

Can comprise in the time of the step specific implementation that issues to descending block gap in the above-mentioned steps 403:

The USF of dispatched users terminal correspondence in descending of each granularity underground at interval.Granularity in the above-mentioned steps 401 is an integer, and assignment interval is the integral multiple of radio block TTI.Assignment interval except can preestablishing, also can obtain assignment interval according to user's request in the base station, comprise the steps: according to the method for user's acquisition request assignment interval

According to described service request, obtain the transmission time interval of user data;

According to the transmitting time of user data, generate the ascending resource assignment messages, the assignment interval in the ascending resource assignment messages is decided according to the transmission time interval of user data.

User terminal sends user data at interval on a up of granularity of correspondence after detecting in descending the USF that assigns.

Wherein, assignment interval in the ascending resource assignment messages is decided according to the transmission time interval of user data, be according to the existing resource situation in the network, the actual transmission demand that correlates user data, such as, the user is by the ftp upload file, it is continuous that data send, the technical scheme that also can use the embodiment of the invention realizes the scheduling of ascending resource, network sends the assignment messages at a definite granularity and interval to user terminal, network can be according to the existing resource situation, and certain 80ms distributes two granularities (each granularity comprises 4 up), is equivalent to this 80ms exactly and all dispatches to this user's usefulness; As find that existing resource is relatively more nervous, then another 80ms can dispatch 1 granularity (each granularity comprises 4 up), is 10ms in the assignment interval of this 80ms.Under the same particle sizes (as 4 of every granularities), the time interval is more little, and the time that each granularity is finished is short more, and new scheduling adjustment is just timely more, dispatches flexible more.

Embodiment two, the method of the realization ascending resource scheduling among the embodiment one is applied in the VoIP business, under RTTI USF mode, user data is that every 20ms sends once, TTI is 10ms, then according to the transmission time interval 10ms of user data, generate the ascending resource assignment messages, and be handed down to each travelling carriage, comprise uplink state sign and granular information in the ascending resource assignment messages, granular information is used to represent up granularity and assignment interval, granularity can be integer, and the assignment interval data are the integral multiple of radio block Transmission Time Interval, in the present embodiment, radio block is for reducing the Transmission Time Interval radio block, and the Transmission Time Interval that reduces the Transmission Time Interval radio block is 10ms.In the present embodiment, granular information adopts the USF_GRANULARITY character of 1bit, and USF_GRANULARITY=1 represents that network can be dispatched two granularities in the 160ms under 4 granularities (each granularity is distributed 4), and the assignment interval in each granularity is 30ms.Can realize that so every 20ms distributes one, then TTI is 10ms, and assignment interval is 10ms.Each MS reads corresponding ascending resource assignment messages respectively, on up of USF indication, according to assignment interval, sends user data at interval.

Referring to Fig. 5, MS1 monitors USF on paired down channel DL PDCH0 and PDCH1, as the USF0 that reads appointment, then on the up channel UL PDCH0 of next cycle correspondence and PDCH1, send data, and on the up channel UL PDCH0 of next 40ms and PDCH1, send next data, till distributing 4 data.In a single day MS monitors the USF of appointment, USF in just can monitor subsequent issue at interval descending, up to last up of this granularity number that send to distribute, USF in continuing again to monitor descending, certainly, in whole process, MS still needs to continue to monitor that other are not the USF in descending that issues at interval.Like this, up of each of distribution all has data to send, and has made full use of channel resource.

Wherein, USF_GRANULARITY is the granular information in the present embodiment, be used to represent up granularity and assignment interval, granular information can also adopt the USF_GRANULARITY character of 2bit, when USF_GRANULARITY was 10, the granularity of representing up was 4 o'clock, and every 20ms distributes one up, TTI is 10ms, and assignment interval is 10ms; When USF_GRANULARITY was 11, the granularity of representing up was 4 o'clock, and every 40ms distributes one up, and TTI is 10ms, and assignment interval is 30ms; Perhaps adopt USF_GRANULARITY character and extension bits information, the granularity that the USF_GRANULARITY character representation is up, extension bits information representation assignment interval, for example USF_GRANULARITY is 1 o'clock, the granularity of representing up is 4, in extension bits, get one, be used to represent assignment interval, when the position of being got in the extension bits is 0, represent that every 20ms distributes one up, TTI is 10ms, and assignment interval is 10ms; When the position of being got in the extension bits is 1, represent that every 40ms distributes one up, TTI is 10ms, assignment interval is 30ms; Certainly can also adopt other can represent the mode of granular information, for example increase the figure place of USF_GRANULARITY, it is increased to more than 2 or 2, so that represent more kinds of assignment interval, perhaps in extension bits, get more than 2 or 2, be used to represent more kinds of assignment interval, realize the scheduling mode of ascending resource more flexibly.

The transmitting time of user data comprises the packing transmitting time of speech frame or the transmitting time of signaling.Under talking state, if speech frame is arranged, promptly the user normally speaks in conversation, and user 20ms sends 1 speech frame packing once one up of then every 20ms distribution; If user 40ms sends 2 speech frame packings once, then every 40ms distributes one up; By that analogy, if user 60ms sends 3 speech frame packings once, then every 60ms distributes one up ... if there is not speech frame, be that the user mourns in silence in conversation, then the transmitting time of user data is the transmitting time of signaling, this signaling be system at random or periodic allocation, be used to represent the signaling of conversing and continuing.

Embodiment three, under RTTI USF mode, are that with the difference of embodiment two up assignment interval is 10ms, and then USF_GRANULARITY is 1bit, and USF_GRANULARITY=1 represents under 4 granularities, and every 20ms distributes one in the 80ms.And the method for salary distribution of the ascending resource among the embodiment two is a dynamic assignment, that is: each MS need monitor USF on the descending PDCH of the up PDCH correspondence of each distribution, when monitoring corresponding USF value, the MS just next radio block on same up PDCH sends upstream data; And the method for salary distribution of the ascending resource in the present embodiment is an extended dynamic allocation, that is: monitor every minimum the beginning of MS sequence number from allocated channel, monitor successively from low to high then, as long as receiving corresponding USF value at certain channel just monitors no longer backward, transmission is up on all subsequent channel of same channel and distribution then, need all not receive USF on each corresponding down channel.

Referring to Fig. 6, MS1 at MS1 on paired down channel DL PDCH0 and PDCH1, and paired down channel DL PDCH2 and the last USF that monitors of PDCH3, as the USF0 that on down channel DL PDCH0, reads appointment, then on the up channel UL of next cycle correspondence PDCH0, PDCH1, PDCH2 and PDCH3, send data, and on the up channel UL of next 20ms PDCH0, PDCH1, PDCH2 and PDCH3, send next data, till distributing 4 data.In a single day MS monitors the USF of appointment, USF in just can monitor subsequent issue at interval descending, up to sending last up of this granularity number, USF in continuing again to monitor descending, certainly, in whole process, MS still needs to continue to monitor that other are not the USF in descending that issues at interval.Like this, up of each of distribution all has data to send, and has made full use of channel resource, and all user data is all sent by up, has guaranteed the integrality that data send.

Embodiment four, and under BTTI USF mode, the transmitting time of user's bag is that every 40ms sends once, TTI is 10ms, and then up assignment interval is 30ms, and then USF_GRANULARITY is 1bit, USF_GRANULARITY=1 represents under 4 granularities, and every 40ms distributes one in the 160ms.In the present embodiment, that MS3 and MS4 adopt is BTTI TBF, and that MS1 and MS2 adopt is RTTI TBF.
